Publication number: 20030236169Abstract: For producing a superconducting circuit, a film (12) consisting of a cuprate superconductor material is generated on a substrate (13), wherein the superconductor material is in the superconducting state at an operating temperature of the superconducting circuit to be produced, and then the film is irradiated by projecting an energetic ion radiation onto the film through a mask (11) positioned at a distance from the film and protecting selected areas of the film from being irradiated, the mask comprising a structure pattern transparent to the ion radiation but otherwise opaque to the ion radiation. Areas (14) not protected by the mask are irradiated with an ion dose being sufficiently low to avoid degradation of the crystal structure of the first film but being sufficient to inhibit superconductivity of the film with respect to the operating temperature; ion doses are preferably in the range of 0.8·1015 and 2·1015 ions/cm2 or below.Type: ApplicationFiled: January 15, 2003Publication date: December 25, 2003Inventors: Wolfgang Lang, Dieter Bauerle, Johannes D.

Patent number: 6548570Abstract: A radiation shielding material is manufactured from an elastomer that is blended with a radiation-absorbing filler material. The filler material comprises a powder of a metal with a high atomic member, or compounds thereof. The filler material is represented by more than 80 percent weight and has a grain size distribution in the range of 20 &mgr;m to 120 &mgr;m. The filler material is mixed with a loading material in powdered form. That mixture is kneaded with the elastomer within a mixer while the temperature is maintained below 180° C. The kneaded mixture is cooled and then cut into strips. The strips are passed through a strainer having a mesh width of between 5 &mgr;m and 1000 &mgr;m. The strained strips are then formed into a foil.Type: GrantFiled: November 16, 2000Date of Patent: April 15, 2003Assignee: Arntz Beteiligungs GmbH & Co. KGInventor: Wolfgang Lange
